*1 A jumper is installed across terminal R1/L11 and terminal P/+, and across terminal S1/L21 and terminal N/-. When using a separate power supply
for the control circuit, remove the jumpers connected to terminals R1/L11 and S1/L21.
*2 The function of these terminals can be changed using the Input terminal function selection (Pr.178 to Pr.189).
*3 Terminal JOG is also used as a pulse train input terminal. Use Pr.291 to choose JOG or pulse.
